Abstract
There is provided a data synchronization circuit for synchronizing a (n+1) (n: natural number) bit bus data synchronous with a first clock with a second clock, comprising: a first circuit for holding the bus data which is synchronous with the first clock and is input at each predetermined timing; a second circuit for generating a first timing signal which is synchronous with the first clock and is corresponding to the predetermined timing; a third circuit for generating a second timing signal which is synchronous with the second clock, from the first timing signal; and a fourth circuit for receiving the bus data output from the first circuit based on the second timing signal, to output the bus data in synchronism with the second clock.
